We will insert Field, Description, Amount, Area, Estimated Cost Per Unit, Actual Cost Per Unit, Estimated Cost and Actual Cost as headings.

Select cell range B4:I4 to format those cells.
Go to the Home tab >> click on Bold button >> select 14 as Font Size.

Insert your values in the Field, Description, Amount and Area columns.

Step 2: Calculate Estimated and Actual Cost

Insert your values in the Estimated Cost Per Unit and Actual Cost Per Unit columns.

Insert the following formula in Cell H5 and press Enter.

=D5*E5*F5

Drag down the Fill Handle tool up to Cell H8 to autofill this formula for cell range H6:H8.

We multiplied the values of Cell D5, Cell E5 and Cell F5 to get the value of Estimated Cost.

Insert the following formula in Cell H9 and press Enter.

=D9*F9

Drag down the Fill Handle tool to autofill this formula for the rest of the cells.

You will get all the values of the Estimated Cost.

Insert the following formula in Cell I5 and press Enter.

=D5*E5*G5

Drag down the Fill Handle tool up to Cell I8 to autofill this formula for cell range I6:I8.

In the formula, we multiplied the values of Cell D5, Cell E5 and Cell G5 to get the value of Actual Cost.

Insert the following formula in Cell I9 and press Enter.

=D9*G9

Drag down the Fill Handle tool to autofill this formula for the rest of the cells.

We multiplied the values of Cell D9 and Cell G9 to get the value of Actual Cost of the fields which do not need to consider the value of area.
